Is the reciprocal of x +. Sally
Tommy and Sally are arguing over the meanings of x* and x Tommy argues that
insists that is the reciprocal of r. Who is correct?
A. Tommy is correct. x' is the reciprocal of +.
B. Sally is correct. x+ is the reciprocal of ".
C. Both Tommy and Sally are correct. x* and x* are reciprocals of each other.
D. Neither Tommy nor Sally is correct. Neither + nor is a reciprocal of the other.

The answer is C because X^-4 is also expressed as 1/X^4. A reciprocal of a number is 1 divided by that number. Therefore, it is seen that X^-4 is the reciprocal of X^4. Also, the reciprocal of X^-4 is 1/X^-4 which becomes 1/(1/X^4) simplifying to X^4. So X^4 is the reciprocal of X^-4, meaning both Sally and Tom are correct.
